Our Core productFoamcore,or Foam board is a very strong, lightweight, and easily cut material used for the mounting of photographic prints, as backing in picture framing, in 3D design, and in painting. It is also in a material category referred to as "Paper-faced Foam Board". It consists of three layers — an inner layer of polystyrene foam clad with outer facing of either a white claycoated paper or brown kraft paper..

The surface of the regular board, like many other types of paper, is slightly acidic. However for modern archival picture framing and art mounting purposes it can be produced in a neutral, acid-free version with a buffered surface paper, in a wide range of sizes and thicknesses.
